4x5 b&w foggy problem

[ryan choi]

when I shoot landscape with my 4x5 camera,sometimes I got weird negatives after processing B&W

kind of foggy grain all of the frame(Please see sample picture)
nothing wrong with my processing method because when I took picture inside
it show me perfectly

is it because of weather condition?

thanks

I was at first inclined to say it was a processing problem. However, if you have negatives from inside that were processed identically and show no problems, then you need to give your camera back/filmholders a good inspection for light leaks.

You don't mention anything about equipment and processing methods, so it's hard to diagnose precisely. It could be something as simple as your pulling the spring back out away from the light seal when removing/inserting the dark slide.

Best,

Are the problem negatives related to a specific weather condition? ie. very cold conditions?

Please show us the entire negative, rather than the positive image. I see lots of flaws that appear to be from processing and from fogging, but not sure. Give more info.
